Whether the network connection 400 and the remote device 20's network connection are disconnected. When the detecting module 102 detects that the network connection between the first network port and the remote device 20 is not disconnected, the sending/receiving module 101 continues to pass through the first network port 400. Data transmission with the remote device in the above manner.

當該偵測模組102偵測到第一網路連接埠400與該遠端設備20之間的網路連接斷開時，該變更模組103獲取該第一網路連接埠400在網路連接斷開時最後一次收、發的資料包，並生成一變更資訊資料包，用於通知該遠端設備20將該第一網路連接埠400傳送的資料資訊通過該第二網路連接埠500繼續傳送，其中，該變更資訊資料包中的源網路位址為該第二網路連接埠500對應的第二網路位址，該源網路埠為該第二埠號，目標網路位址為該遠端設備的第三埠201對應的第三網路位址，目標網路埠為該遠端設備20的第三埠號。該變更資訊資料包中還包括有網路斷開前與該遠端設備20通信的第一網路連接埠400對應的網路位址以及埠號(即變更前的網路位址及網路埠號)以及變更後與該遠端設備20進行通信的第二網路連接埠500對應的網路位址以及埠號。 When the detecting module 102 detects that the network connection between the first network port 400 and the remote device 20 is disconnected, the change module 103 acquires the first network port 400 in the network. The last time the data packet is received and sent when the connection is disconnected, and a change information package is generated for notifying the remote device 20 to connect the data information transmitted by the first network port 400 to the second network port. The 500 continues to transmit, wherein the source network address in the change information package is the second network address corresponding to the second network connection 埠500, and the source network is the second nickname, the target network The path address is the third network address corresponding to the third port 201 of the remote device, and the target network port is the third port number of the remote device 20. The change information package further includes a network address and a nickname corresponding to the first network connection 埠400 that communicates with the remote device 20 before the network is disconnected (ie, the network address and network before the change) The nickname) and the network address and nickname corresponding to the second network port 500 communicating with the remote device 20 after the change.

該發送/接收模組101將該變更資訊資料包通過該第二網路連接埠500發送至該遠端設備20。該遠端設備20接收到該變更資訊資料包後，讀取該變更資訊資料包中變更前的網路位址及埠號、網路斷開前第一網路連接埠400最後一次收、發的資料包對應的序號以及變更後的網路埠對應的網路位址及埠號，然後根據上述讀取到的資訊將與第一網路連接埠400的資料通信變更為與第二網路連接埠500的資料通信。生成一第三資料包並將該第三資料包發送至該第二網路連接埠500，其中在本實施方式中，該遠端設備 20與該路由器10進行資料傳輸時，每個資料包中均包含一唯一的序號，當該偵測模組102偵測到該遠端設備20與該第一網路連接埠400之間的網路連接斷開時，該變更模組103獲取該第一網路連接埠400在網路連接斷開前最後一次收、發的資料包資訊，並根據該網路連接斷開之前該第一網路連接埠400最後一次收、發的資料包資訊生成該變更資訊資料包，其中該變更資訊資料包中還包括該第一網路連接埠400與遠端設備20的網路連接斷開時最後一次收、發資料包對應的序號，當該遠端設備20更改為與該第二網路連接埠500進行資料傳輸時，該遠端設備20發送至該第二網路連接埠500的資料包為接續該第一網路連接埠400斷開連接之前最後一次接收的資料包，具體地，該遠端設備20接收到該變更資訊資料包後，生成一第三資料包，該第三資料包中的源網路位址為該遠端設備20的第三埠201對應的網路位址，源網路埠為該第三埠號，目標網路位址為該第二網路連接埠500對應的網路位址，目標網路埠為該第二網路連接埠500的埠號，該第三數據包中的資料資訊為接續該第一網路連接埠400斷開前最後一次接收到的資料包中的資料資訊。從而，該發送/接收模組101通過該第二網路連接埠500替代該斷開的第一網路連接埠400繼續發送/接收資料，使得第一網路連接埠400的資料傳輸斷開時可以即時地、自動地切換至第二網路連接埠500，不影響到用戶的使用。 The transmitting/receiving module 101 sends the change information package to the remote device 20 through the second network port 500. After receiving the change information package, the remote device 20 reads the network address and nickname before the change in the change information package, and the first network connection 埠400 before the network disconnects. The serial number corresponding to the data package and the network address and nickname corresponding to the changed network ,, and then changing the data communication with the first network connection 埠400 to the second network according to the information read above.

When the detection module 102 detects the network between the remote device 20 and the first network connection 400 When the road connection is disconnected, the change module 103 obtains the last packet information received and sent by the first network port 400 before the network connection is disconnected, and the first network is disconnected according to the network connection. The last information received and sent by the road connection 400 generates the change information package, wherein the change information package further includes the last connection between the first network port 400 and the remote device 20. The serial number corresponding to the data packet sent and sent by the remote device 20 to the data packet of the second network port 500 when the remote device 20 changes to perform data transmission with the second network port 500 To receive the last received data packet before the first network connection 埠400 disconnects, specifically, after receiving the change information data package, the remote device 20 generates a third data package, the third data package. The source network address in the remote device 20 The network address corresponding to the third port 201, the source network port is the third port number, and the target network address is the network address corresponding to the second network port 500, and the target network port is the The second network is connected to the nickname of the 埠500, and the data information in the third data packet is the data information in the last received data packet before the disconnection of the first network connection 埠400. Therefore, the transmitting/receiving module 101 continues to transmit/receive data through the second network port 500 instead of the disconnected first network port 400, so that the data transmission of the first network port 400 is disconnected. It is possible to switch to the second network port 500 immediately and automatically without affecting the user's use.
